Abstract: Aiming at the problems existing in collection part of traditional farm field meteorological information remote monitoring system, such as difficult routing, high cost and distance limitation, this paper presents a scheme of wireless network collection node based on GSM with its wide covering, rapid and low price, and describes hardware architecture, communication principle and software implementation. The experiment shows that the system is reasonable and feasible, it can realize timely collection, stable transmission and real-time alarm of farm field meteorological information.
